CEMENT-APPLYING MACHINE.

Specification of Letters Patent.

Patented May 15, 1917.

Application filed .Tune 5, 1916. Serial No. 101,840.

To all whom it may concern:

Be it known that I, WILLIAM F. LAUTEN- SCHLAGER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Cement-Applying Machines, of which the following is a specification.

My invention relates primarily to cementstring controlling means, and means for wiping the laid cement, and is an improvement upon the cement applying machines shown, described and claimed in my applications for Letters Patent of the United States, Serial No. 39,802, filed July 14th, 1915, and Serial No. 46,268, filed August 19th, 1915.

Cement applying machines to which my improvement relates are applicable for providing the margins of flexible material, such as leather, cloth and fabrics of various kinds with a narrow band of cement in the manufacture of shoe-uppers, gloves, pocketbooks and containers of various kinds. These margins are skived at times, especially when the flexible material operated upon is in the nature of shoeuppers.

The cement employed in this art usually contains rubber, and is tacky or gummy at the time of its application, and has a tendency to form strings which may at times take the form of a film of cement between the point of cement application to the margin and the cement-applier. The cement also has a tendency to form drops or small balls which are liable to drop upon the material, which is detrimental.

I have also found that when employing a rotary cement-applier in cementing convexly curved margins that the cement strings have a tendency to pull the cement away from the extreme outer edge of the margin and thereby leave the said extreme outer edge uncemented.

In order to overcome the objections stated, I have provided a yieldable cementcontrol acting to wipe the cement-strings or film lengthwise of the margin and to direct surplus cement back toward the cementapplier.

It is the object of my invention further to provide a yielding cement-control at the feeding-out side of the cement-applier, acting preferably to resiliently wipe the applied cement, and further to provide a brush at the feeding-out side of the rotary cement-applier with relation to which the cement-applier has rotation, and the invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is an end elevation of so much of a cement-applying machine as is necessary to illustrate my invention.

Fig. 2 is a front elevation of the same.

Fig. 3 is a rear elevation of the same.

F ig. 6 is a vertical cross-section taken on the line 6-6 of Fig. 2.

Fig. 7 is a vertical cross-section taken on the line 77 of Fig. 2.

Fig. 8 is a perspective view of the cementapplying means showing the cement being applied to the margin and viewed from the feeding-out side and away from the operator.

Fig. 9 is a perspective view of the same, viewed toward the operator and from the feeding-in side; and,

Fig. 10 is a side elevation, showing the cement application upon the margin of a piece of material, the material being cut away proximate to the plane of the feedingout side of the cement-applier.

The cement applying instrumentalities may be mounted upon a suitable frame, for instance as shown in my aforesaid application, Serial- No. 39,802, and the cementapplier rotated and the feeding of cement caused in manner as therein shown and described.

Instancing this arrangement, 21 represents the main frame, which may have a laterally and forwardly projecting arm 22 extending therefrom. A cement-pot 23 is fixed in a bearing 24 of the arm. A cementpassage 25 extends therefrom to a cementvalve 26 for controlling the flow of cement. 29 is a cement-supplying roller at the lower end of the cement-passage 30 in the valve.

The cement-supplying roller is provided with cement-supplying recesses 31, arranged to receive the cement and feed the same to a cement-applier 32, exemplified as a rotating brush.

The cement-supplying roller is instanced as rotating in the direction of the arrow a. The cement-applying brush is instanced as rotating in the direction of the arrow 5. Means for rotating these devices may be instanced as a shaft 35, rotated in suitable manner, as by means of a pulley 36, and having thereon a gear 37. The gear 37 meshes with a gear 38, fast on a shaft 39, j ournaled in a bearing 40 in the forward extension 41 of the arm 22. The gear 38 meshes with a gear 42 on a shaft L3, journaled in a bearing i i of said forward eX- tension. The cei'nent-applier 32 is mounted about the shaft 43 in manner hereinafter explained. i

The shaft 39 has a gear l6 fixed thereon, which meshes with a gear 47 fast on a shaft 48, journaled in bearings 49, and having the cement-supplying roller 29 fixed thereon.

The margin of the flexible material is arranged to move crosswise of the cement-applying brush, instanced in the present exemplification as accomplished by manual means, being moved past the cement-applying brush crosswise thereof by the hands of the operator, and guided on a forwardly eX- tending support 51, located at the feeding-in side of the rotary cement-applying brush, and by a gage 52 adjusted upon said support for increasing or decreasing the width of the margin presented to the cement-applying brush during cement application.

It is movable, for instance, forward and back on the support 51 and fixed in place by a clamp-screw 53, which passes through a slot 54 in the support and has threaded connection 55 with the gage. The gage has an upper flaring finger 56 thereon. The margin of the material is arranged to be received in the recess 57 between the finger and support for guiding the same, this recess having a gradually widening mouth for readily receiving the edge of the margin.

The support may also be raised or lowered and held in adjusted positions by means of clamp-screws 58 received through a slot 59 in the shank 60 of the support, and threaded in threaded apertures in the arm 22.

The brush is provided with annular rows of bristles, separated by rings 66 about a bushing 67. The bushing is arranged to be adjustably secured to a sleeve 68 by means of a set-screw 69. The sleeve is rotativcly fixed to the shaft 43 by means of a pin 71 in the shaft received in an end slot 7 2 in the inner end of the sleeve. The outer end of the sleeve is spaced from the outer end of the shaft 43 for forming an annular recess 73 between the shaft and hub of the brush in line with the sleeve.

The material-supporting face of the support or horn is arranged to be adjusted up or down according to the thickness of the leather or material being cemented. The material 74 being cemented may be skived as shown at 75. The material-supporting face of the support or horn approaches the axis of the rotating brush at its rear, thereby insuring that intimate contact between the outer edge of the margin being cemented and the rotary brush is maintained.

111 operating the machine, in the present exemplification, the operator is seated in front of the cement-applying head, as viewed in Fig. 2, that is, facing the front of the machine, which front is marked fin Fig. 1. The normal direction of feeding the material is indicated by the arrow 0 in Figs. 8 and 9, the side cl of the rotary ce1nentapplier being therefore the normal feeding-in side, and the side 0 of said part being the normal feeding-out side thereof.

The gage with its support is located at the feeding-in side of the rotary cement-applying brush and its edge proximate thereto is preferably spaced from the bristles of the brush by a slight space 76, for permitting the material to be flexed about the periphery of the brush at its point of cement application, as indicated at 7 7 without undue flexure of the bristles of the brush and for insuring intimate contact between the margin being cemented and the periphery of the brush.

This space also permits the ready passage of crossseams, when such are contained in the margin, as when cementing closed vamps.

The degree of pressure of the margin of the material upon the periphery of the brush is readily regulated by the force applied by the hands in stretching the material between the hands at the point of cement application, and also by the direction above or below the plane of the cement-applying portion of the brush in which the feeding-out portion of the margin is held.

The feeding movement of the material may be accomplished by manual manipulation or by mechanical feeding means.

The movement of the cement-applier crosswise of the margin causes a stringing, as shown at 78, of the cement at the feeding-out side of the brush, this stringing sometimes taking the form of a thin film of cement.

The. stringing is especially noticeable when the cement-applier is a rotary cementapplying brush, which I have found best for cement application, as the pressure of the margin upon the bristles and the feeding of the margin lengthwise of the margin and crosswise of the rotating brush, causes lateral flexure of the bristles of the brush at the point of cement application, and a tendency of the cement to follow the feeding movement of the margin resulting in the stringing mentioned.

In order to control the said stringing of the cement and preferably also to aid in the laying of the cement, I provide a yieldable cement control 80 at the feeding-out side of the cement-applier.

This cement control is shown as a brush, with relation to which the cement-applying brush has rotation. It is shown mounted on a plate '81 received about the axis of rotation of the cement-applying brush, being provided with an annular flange 82 at its middle portion which is received about the shaft 4L3 in the annular recess 7 3. The plate adjacent to the flange contacts the hub of the cement-applying brush, as shown at 83, for preventing seeping of cement to the brush-shaft. It is held on the shaft by means of a screw 84 which has threaded connection. with the end of the brush-shaft.

In order to prevent rotation of the plate with the shaft and cement-applying brush, it is provided with a tail-piece 85, arranged to contact the cement-applying head, for limiting its rotative movement about the shaft in one direction, but permitting .an oscillation of the plate about the shaft, if such should be desired, for cleaning purposes.

The plate is provided with a laterally sloping wall 88 at the side of the initial part of the cement-feeding portion of the rotary brush, adjacent to the cement-supplying roller, forminga clearance space 89 for the cement at the feedin -out side of the rotary brush which tapers toward the brush. This clearance space permits ready wiping of the cement off the cement-supplying roller by the rotary brush.

This laterally sloping wall merges into a radially extending wall 90, which extends substantially to or beyond the peripheral line of the rotary brush, in close proximity to the bristles of the rotary brush, and, in connection with said first-named wall, directs the cement at the feeding-out side of the rotary brush toward the ends of its bristles.

The peripheral edge of the plate at that portion thereof proximate to the normal cement-applying portion of the rotary brush, and in advance of the material-supporting surface of the material-support, is located inwardly from the longitudinal projection of the periphery of the rotary cement-applying brush, as shown at 91, so that the bristles of the rotary brush may project beyond said edge.

The character of the cement employed,

78. It is understood that the bristles of the rotary brush are flexed during cement application and move past said outer edge in contact therewith. These strings of cement normally extend from said margin to the periphery of the rotary brush and would normally follow the periphery of the rotary brush in its rotation and cause the end of the rotary brush and the plate to be in time covered with cement, which would eventually drop in drops or lumps on the material, and be uncleanly. a

In order to prevent this undesirable condition, I have provided the yieldable cement control, which preferably extends rearwardly of the margin and beyond the periphery of the rotary cementapplier crosswise of the margin being cemented. (See Fig. 10).

The yielding cement control is preferably in the form of a narrow brush extending crosswise. of the margin, the bristles of which are resilient and act to arrest the cement strings and lay the same toward the margin being cemented, so that the extreme outer edge of the margin may have cement applied thereto, and act also to brush the cement lengthwise of the margin. The

bristles of the cement-control brush preferably act to brush across the oblique ridges 93 of cement formed by the rotary cement applying brush upon the margin fed crosswise thereof, to crossline the same as indicated at 94 in Fig. 8. The yielding cement control further tends to arrest the surplus cement and the rotary cement-applier takes the surplus cement with it in its rotation to the cement-supplying roller, and thereby prevents the dropping of drops, beads or tears of cement on to the material being cemented.

The resilient bristles of the cement-com trol brush have a continual tendency to move toward the rotary cement-applier, and act resiliently upon the margin. The operator is thereby aided in controlling the thickness of the cement-application, as the manual raising of the outgoing stretch of the material being cemented increases the pressure upon said control for decreasing the ready passage of the applied cement, although the resilience and separation of the bristles of the cement-control brush avoid the wiping of the applied cement from the margin. The movement of the outgoing stretch of the material away from the line of the axis of rotation of the ro tary cement-applier will permit the more ready passage of the applied cement on the margin past said control.

The yielding or resilient feature of the cement control has the further advantage that thereby seams are allowed to readily pass the control, and, if desired, to permit seams to be moved. past the cement control in reverse direction for allowing the seams to be passed back and forth across the rotary cement-applier, for instance, when it is desired to apply cement under the flaps of the seams.
